Acceptable Calculators

What is and isn't allowed for the SAT® on test day

Every mathematics question on the SAT can be solved without a calculator. However, using a calculator may be helpful for some questions. Scientific or graphing calculators are recommended.

Calculator primer

  • Students should bring a calculator with which they are familiar and comfortable. Their degree of familiarity with the operation of a calculator may affect how well they do on the test.
  • Students should bring extra batteries and, if possible, a backup.
    calculator—test center staff do not have batteries or extra calculators.
  • Students are not required to clear the memory on their calculators before testing.
  • Students are not permitted to share their calculators. Students who use their calculators to share or exchange information during the test are dismissed and their scores are canceled.
  • Students using a calculator with a large (characters one inch or more high) or raised display that might be visible to other test-takers are seated at the discretion of the test supervisor.

The following are not allowed:

  • Laptops or other computers, tablets, cell phones, or smart phones
